10. ASSEMBLER RESERVED WORDS
10.1 Mask Option Directives
When creating the
PD62A program, it is necessary to use a mask option directive in the assembler’s source
program to specify a mask option.
10.1.1 OPTION and ENDOP directives
The assembler directives from the OPTION directive to the ENDOP directive are called the mask option definition
block. The format of the mask option definition block is as follows:
Format
Symbol field
Mnemonic field
Operand field
Comment field
[Label:]
OPTION
[; Comment]
:
ENDOP
10.1.2 Mask option definition directive
The assembler directives that can be used in the mask option definition block are listed in Table 10-1.
An example of the mask option definition is shown below.
